From a layman's perspective, WOW. I have to admit I don't have a clue about a few of the issues you addressed - I'm just a hobbyist with a love for numbers - but it (your concept) does have a certain "elegance" about it that makes it a fun read
I don't understand the use of the term "infinities", and that may only reflect my ignorance. Is there a scientific definition of it that is not in common use? Is there another term that may be more appropriate?
And the question of how E=mcc is "broken" bothers me also, not in "how did it get broken" but in "in what way is it broken". Is it broken by alteration of the speed of light? Or a significant departure in mass or energy values? The well educated here may have no problem with your description, so you needn't rush to answer, but when you have time, a layman's description of these terms would be helpful.
Would your theory allow some form of mapping of these membranes via galactic positions?
Would the CMB be stronger near younger galaxies than near old ones?
What mechanism would prevent a galaxy from forming on top of another? Or is such a mechanism even required? If matter/energy is constantly being added to the universe, should there be regions in which galactic density is dramatically higher than others? (That may already be a confirmed fact - if so, I apologize for my ignorance).
Do you have ideas as to the source of the "strings", or are they aspects of an earlier "bang" altogether?
Sincerely,
Derrick Baumer
